How come the Blender 2.83 Splash Screen by Ian Hubert takes so much less time to render than my Doughnut tutorial?
While Cycles is a &quot;path tracer&quot;, Eevee is rasterizer.
&quot;Unlike Cycles, Eevee is not a raytrace render engine. Instead of computing each ray of light, Eevee uses a process called rasterization. Rasterization estimates the way light interacts with objects and materials using numerous algorithms. While Eevee is designed to use PBR principles, it is not perfect and Cycles will always provide more physically accurate renders. Because Eevee uses rasterization it has a large set of limitations.&quot;

for example almost all game engines are Rasterizer. That way we can &quot;fake&quot; most stuff to look like the real deal.
And you are in luck. Eevee and Cycles are very close togther in node setup so your work is have been cut in half already. But what you do need to learn is the Eevee limitations.
